Rainfall will be seen reducing on November 20th. In fact, on November 21, rain will be even less for the city.
These rains are due to a Cyclonic Circulation that is seen off the Tamil Nadu Coast. A trough is also seen from circulation along the coast to the centre of the storm. A convergence is seen over the coastal parts of Tamil Nadu, which will cause rains over the region.
